摘要：

常规压裂装备存在效率低、环境污染大以及国内市场水功率保障不足等问题,不能满足国内页岩气开发扩大化和促进产能提升的需求,因此,推荐在页岩气压裂工程中应用全电动压裂装备。通过重点分析全电动压裂装备及技术在常压页岩气资源区块示范应用效果,论证其在页岩气效益开发和绿色低碳发展方面的优势,结果表明：全电动压裂装备能稳定实现高负载、高可靠和连续大排量施工,且施工效率高。相比燃油压裂装备,可节约施工设备、动力、人工以及维护等方面的综合成本40 %以上,污染排放总量减少70 %,有效控制厂界噪声,有利于推动实现常压页岩气效益开发和建设绿色矿山企业。

Abstract:

With the expansion of domestic shale gas development demand and production capacity, the all-electric fracturing equipment and technology has become the recommended application technology for normal pressure shale gas fracturing engineering due to the low efficiency of conventional fracturing equipment, large environmental pollution and insufficient water power guarantee in the domestic market. This paper focuses on analyzing the demonstration application effect of all-electric fracturing technology in atmospheric shale gas resource block, demonstrating its advantages in shale gas benefit development and green and low-carbon development. Results show that the all-electric fracturing all-electric case can achieve stable high load, high reliable and continuous construction of the large displacement, high construction efficiency, The comprehensive costs of construction equipment, power, labor and maintenance, etc., fell by more than 40 %, pollution emissions by 70 %, the effective control of noise at boundary of atmospheric pressure shale gas can effectively help realize benefit the development and construction of green mining enterprises of the forehead.

Key words: atmospheric shale gas, full electric fracturing, demonstration application, benefit development, green low-carbon
